Vasopressin, as the name tells, increases the resistance of the peripheral vessels and thus increases arterial blood pressure. Another thing to point out is the fact that the hormone's action is to flush out water from your body--the opposite of what a diuretic would do. A person taking a diuretic will have lower blood pressure after using it ,while vasopressin's name implies that BP is increased.
